Running and leaping: 40-60 ft up.
I wonder how Sakis and torquatus segregate themselves? Must be serious competitors!
Then we hear more tamarin Whistles in nearby scrub or low forest. Then we catch glimpse of group. At least 3 inds 10-20 ft up second growth trees.  Utter LSN's and Trll's when they see us.  Sound rather fainter than the corresponding notes of the Caquetá animals. But they move off before I can get a good view of their back pattern.
F says that the local tamarins go in large groups. 12 and more.
Stop observations 12:40 p.m.
COMMENT: There must be (or have been) approximately 10 species of monkeys in this general region. Just as in the Caquetá. Is this the most that most regions can support?
Callicebus torquatus certainly is a species of higher more open vegetation than moloch. Until I saw the Sakis, I thought that it must fill the "Saki niche" here. But obviously it does not. At least not completely. Is it more of a nut eater than Pithecia? (This would be surprising in view of the dentitions of the two types.) What is the size difference between the two types?
According to F, the Pygmies make holes in only one kind of tree. Something called "guama".
He also says that the local indians here hunt all kinds of monkeys. Down to and including Saguinus.
